Just out of curiosity,do you believe that each region has the best possible climate due to a supreme being?
Each region has the best posible climate because over the last few generations it evolved to be adapted to the climate of that region. The roads, the houses, the bridges, the local crops, the calendars of activity are all adapted to the climate of region that can sustain them.
Research has shown that these climates have not been stable over time; often changing dramatically.
That is both true and false depending on the temporal and spatial frame that you choose. In time frames relevant to the climate change debate that is false. The climate have been stable for thousands of years. If the climate was unstable we wouldn't have evolved to be the dominant species of the planet. Of course that doesn't mean the climate hasn't changed, sometimes dramatically. It only means that the changes were easily absorbed by the global civilization, thus we define the climate as stable.
Why do you think that today that they are the best possible?
Because everything we have built is optimized for the environment where it will work. If those parameters change our infrastructure might fall outside the range of those parameters and not be optimized anymore. Thus the best climate is the one we built everything for.
Change can be good, bad, or indifferent. Broadly claiming that change is bad is a defeatist attitude.
Yes. For example lets say you have your work area set up in certain way and someone comes around and changes everything. In that case change is most likely bad. You have reasons to have everything setup the way you have it setup. However it could be that some of the changes made you realize a better way to do something, in which case change is good.
That's the type of change that climate change will be.
Broadly claiming that change is bad is a defeatist attitude.
No one is claiming that change in a general sense is bad. I'm claiming that a particular type of change, climate change, is bad. And it is not defeatist it is realist. It is very likely that most changes in climates will be bad, because, by far, most climate changes are bad in the short term more often than not. That this particular climate change is global, not local make it even worse.
As Teddy Roosevelt once said, “There can be no life without change, and to be afraid of what is different or unfamiliar is to be afraid of life.”
That does not apply. I'm not afraid of climate change because is something different. I'm afraid of climate change because chances are it will be very very bad.
